I have an old Multiplus 24/3000/70 (still has VE-Bus, it's the 19xxxx model), a BMV 712 and a 30a smartsolar MPPT. I've purchased a large "drop-in" LiFePO4 battery with no LT cutoff and no external comms. Can anyone assist with low temperature cut off?
- I know how to do this with the MPPT - (either by using a temperature sensor to BMV712 or using a Smart Sense and linking with Bluetooth.
- The question is, how do I cut off the Multiplus (someone accidentally turns generator on to charge for instance and it's below 5 degrees in battery compartment. Do I use the same sensor and use an assistant and 2 wires (not sure how this works) from the BMV 712? Should I use a smart sense bluetooth connection for MPPT and a separate wired temperature sensor?
Any help would be really appreciated.
